Letters Patent No. 96,116, dated October 26, 1869.

IMPROVEMENT IN BUNG-S.

T116 Schedule referred to in these Letters Patent and making part of the sama being, first, that they allow no escape ofthe compressed a-ir, which invariably occurs with the old system, or what are in present: use, no matter how well they may be contrived or fixed; and secondly, that they' aremore economical, in that they last out several barrels or vrats, and at the same time preserve the quality and strength of the liquid therein contained. y The accompanying drawings will clearly elucidate ny system, which consists of two essential parts, that is to say, first, the body A, (see Figure l, which represents a bung of this description in its entirety, and i asection of which is shown by Figure 2;) and sec ondly, ot' the cap or plug B. g

The body consists of a socket, with exterior dentic nlations or grooves P, -so that when the bung is once fixed in the barrel or vat, having' previously dipped it in resin or other glutinous matter, it adheres so tenaciously to the barrel that the. grooves P ei'ectually prevent its removal wit-hout taking the barrel to pieces,

the closure heilig so hermetical that it prevents the smallest quantity of air passing between the body and the wood of the barrel.

The interior of the body is furnished with screw threads V, for receiving the screwof the head o r plug V. This latter `is of one single piece,"shown in Figure 3, the upper part, which, in the drawing is square, but may be made of any other polygonal form, admitting of the adaptation of a key for removing or fixing it, as desired.

The upper part of the plug B may be made as in Figure 4, in which case it is turned by means of a small metal shaft passed through the opening o.

Below the flange D is placed a leather or Indiarubber washer, C, to prevent the passage of air into the vessel. v

The plug represented in figs. 3 and 4 is intended for use while the barrels are being moved, andis replaced by that represented by Figure 5 when it is intended to draw off the liquid This double plug is screw-cut at the lower part, V, for tting the screw V.

This yis also supplied with a washer, c, below the ange D, serving to intercept any passage of air into the interior of the barrel or vat'.

The upper part has a screw fitting in the screwthreads V, arranged inside the crown. (See Figure 6.) The double plug, fig. 5, is bored down its centre e its whole length, so as to give to the barrel' all the requisite pressure. of air for drawing oli the liquid.

The head, fig. 6, has in its centre a small cylindrical tube, with a rim at the lower part, shown in Figure 7, and serving to maintain the end of the India-rubber or gutta-percha tube employed for conducting the air necessary for p'roducing the requisite pressure. n Y By the foregoing description, it will be observed that my system of bung advantageously replaces those in present use, and does away with the opening or vent for admitting the air, andt-hus preserving the barrels or vats; and experience has proved that beer especially is improved by the adoption of my system, as there is no loss of air, and consequently the liquid does not become iiat, and preserves. all its strength and quality.

What I claim, and desire to secure by Letters Patent, is-

The system of metallic bung hereinbefore described, and illustrated by the accom panyingdrawngs. Witnesses: Von. A. HOUDAILLE.
